If you're out and about in Perthshire this May, you might come across an unusual and somewhat unsettling sight.
Located approximately 18 miles west of the town of Pitlochry is the remains of Dunalastair House. The imposing structure resembles a large mansion or castle, but the closer you get the more you realise it is nothing but a skeletal ruin.
The haunting site, which in recent years has become a favourite spot amongst explorers and adventurers, was in fact once a grand estate. It might be hard to believe, but not even 100 years ago it was a school for Polish children.
